    Enhancing Fire Scene Investigations Through New Technologies

    Abstract: The application and limitations of field-portable Gas Chromatography/Mass Spectrometry (GC/MS) to fire investigations was the focus of this project. Today's fieldportable GC/MS systems were found to provide lab-quality data for volatile hydrocarbons but the interpretation of that data proved challenging for field operators. On-line access to lab experts is essential. Scene investigators felt that data generated at the fire scene is useful, especially for public agencies who often must wait months before receiving lab results. Scene sampling using SPME has proven problematic due to the over-saturation of the sensitive SPME fibers and their rapid loss of adsorbed compounds. Sampling at ambient temperatures limits the range of identifiable.products. Evidence sampling is enhanced with the use of sensitive PIDs (photoionization detectors). as a supplement to canine searches.

    Enhancing Fire Scene Investigations Through New Technologies

    Introduction

    Fire investigators rely on detection and lab analysis of samples (typically burned debris) to reveal the presence and identity of ignitable liquids as evidence of the incendiary nature of the fire. For many years fire investigators relied on their own sense of smell to detect possible accelerants in fire debris. With the realization of the health hazards involved, investigators used a variety of hydrocarbon detectors. Combustible Gas Detectors (CGD) using a sampling pump and a heated-wire sensor were very popular and worked well but could be overwhelmed if exposed to very high concentrations of flammable vapors and had numerous interferences. Solid-state detectors offer fail-safe use but have no pumps and must rely on vapors drifting into contact with the sensor and then dissipating, resulting in slow, stop-and-start searching.

    The ppbRAE 3000® detector used in these tests is a photoionization detector (PID) with a continuous pump drawing air through the sensor and back out again. (See Figure 1). It will be described in full in a later section. The sensitivity of the ppbRAE 3000® used here can measure hydrocarbons down to a few parts per billion (ppb).[1] This is contrasted with the lower detection limit for other “sniffers” on the order of a few parts per million (ppm), or the normal human nose with a threshold for gasoline of around 1 ppm. [2] For reference, the estimated threshold for trained, certified accelerant detection canines is on the order of 20 ppb (parts per billion). [Unpublished data from tests at fireK9.org testing February 2019 by authors.] With its small sample volume and fast pump, the ppbRAE® clears quickly, making rapid searches of a room possible.

    Canine detection teams have been in use by fire investigators since they were introduced in the late 1980’s. They have tremendous sensitivity, coupled with great speed in

    This project, from its outset in 2013, has been to assess the feasibility of employing GC/MS (gas chromatography/mass spectrometry) at fire scenes to identify possible accelerants with sufficient accuracy to allow the investigator to further the investigation (search warrants, interviews, etc.) based on reliable lab results. This study involved the use of several different field-portable GC/MS systems designed for HazMat/WMD responses, some of which have been reported on previously. The project phase reported here had two objectives. The first was to analyze and compare GC/MS data from both field and bench GC/MS analyses of debris from live fire tests and from 15-30 fire scenes where ignitable liquids were suspected. In concert with canine searches and advanced technology hydrocarbon detectors (sniffers), evidentiary samples were taken, field-tested, and sent to an accredited fire debris lab. Second, once the quality of data was assured, investigators evaluated the impact on decision making and fire investigation outcomes from obtaining reliable GC/MS data at the fire scene. These evaluations were not intended to replace canines, “sniffers”, or accredited lab analysis for judicial processes, but to improve the information investigators could use while still at the scene.

    The IAAI Board of Directors congratulates the Constitution and By-Laws Committee for changing their Policies and Procedures to allow for public comments to be posted prior to the opening of the ballot. This positive change in the procedure for posting of proposed changes to our Constitution and allowing for an open public comment period is welcomed.

    The Board of Directors met on January 9th, 2021 during a regularly scheduled Board meeting, during which a review of the two proposed amendments was an agenda item. After a discussion and debate on the merits of the proposed amendments, the Board voted to oppose both proposed constitutional changes. The Board believes these two proposed amendments would inhibit the ability of the Board and the office of the President to effectively conduct the business of the IAAI, as the elected representatives of the membership. The purpose of the Constitution is to provide the Association with a framework by which to operate, not manage the operations. The only committees mandated by the constitution are found in Article V “Committees”. Other than these eleven Standing Committees, all other committees or task groups are appointed by the President. Any committee or task group not reappointed by the new President, ceases to exist. The purpose of a Task Group is to research a specific issue at the direction of the Board. The makeup of the Task Group should be based on the issue to beaddressed and not restricted because a member serves on other committees or Task Groups. The President and the Board should have the freedom to appoint the people to a Task Group that are best suited to address the issue at hand. Placing restrictions on who can be appointed and for how long a Task Group can be in place would inhibit the ability of the leadership to effectively conduct the work of the association. It is therefore the position of the Board of Directors that these proposed Constitutional changes are not passed.

    CHAPTER MEETINGS AND ACTIVITIES? YesOFFICES HELD STATE/PROVINCE CHAPTER? Iowa Chapter Director, 2nd VP, 1st VP, PresidentPLEASE LIST ANY INTERNATIONAL OFFICES HELD, SPECIAL PROJECTS OR COMMITTEE WORK, INDICATING YEARS OF SERVICE. Board of Director since 2015, Editorial Review Board Chair since 2015, CFITrainer Co-Chair since 2019DESCRIBE, IN 100 WORDS OR LESS, WHY YOU FEEL YOU ARE QUALIFIED FOR THIS POSITION: I have been on the Board of Directors since 2015 and I have attended 14 ITCs over the years. I was the Iowa Chapter President after many years as a Director. I was subsequently awarded a Lifetime Membership Award by the Iowa Chapter. I am the Chair of the Editorial Review Board committee and the Co-Chair of the CFITrainer Committee, a IAAI CFI and a retired ATF CFI. I continue to work fire scenes as well as perform contract instructor duties for ATF.WHY DO YOU WANT TO BECOME A DIRECTOR OR OFFICER OF THE IAAI? After spending two terms as a Director, I wish to continue in my service to the members as their representative so that I can continue to move the Association forward.WHAT DO YOU BELIEVE ARE YOUR BEST LEADERSHIP TRAITS, AND HOW WOULD YOU USE THEM AS A DIRECTOR OR OFFICER OF THE IAAI? I believe that I can build consensus in the board room. When decisions are made, whether my position or not, we should move forward as a Board. I tend to be methodical in that I believe the Board should move in a deliberate path and at a pace that is most efficient for progressing the interests of the membership. I would also strive for professional, constructive discussions so that the best interest of the members can be represented.WHAT STEPS DO YOU BELIEVE SHOULD BE TAKEN TO GROW MEMBERSHIP? I believe that we should work towards enhancing the benefits of membership and be better at promoting our Association.

    HOW WOULD YOU PROPOSE TO IMPROVE RELATIONSHIPS AND COMMUNICATIONS BETWEEN THE INTERNATIONAL AND CHAPTERS? I believe that the relationships with our Chapters have improved, but that we need to continue our efforts in that area. We need to ensure that the Chapter liaisons are effective and have good relationships with their respective Chapters. We need to continue with our Chapters Presidents conference calls and listen to and bring the Chapter President’s concerns to the Board for consideration.WHAT ARE YOUR RECOMMENDATIONS FOR FUTURE FUNDING OF CFITRAINER.NET? The Board has had lengthy discussions on this topic. The general consensus is that we should use a two prong approach. One would be to actively seek donations or contributions from members/users and private industry. Part two would be some form of user fee. This portion is complex in that we have many different types of users, from individuals to Universities. I believe we could structure a minimal yearly fee for individuals, if we had to, and work out financial agreements with Colleges, Universities and Agencies that use our training platform.OTHER THAN TRAINING FIRE INVESTIGATORS, WHAT TWO OR THREE OTHER ELEMENTS DO YOU CONSIDER AS CRITICAL TO THE MISSION OF THE IAAI? In conjunction with training fire investigators, the IAAI needs to promote and advance the profession of fire and explosion investigations. Therefore, we need to stay up to date on the latest research, science and legal issues related to our profession. The IAAI needs to promote, encourage and when possible, participate in research and testing. Due to our lack of physical testing capabilities, we need to partner and/or participate as much as possible.This dovetails into a second part of what we can do as an organization. The IAAI should strive to be the conduit of all the most current and relevant information as possible to our membership. As a global organization of over 10,000 members, if we provide as much information as possible to our members, this can be the method for promoting our profession worldwide. The information we provide should be current and as accurate as possible, all the while keeping in mind that not everyone will agree with the information presented. Our members should have as much information as possible and then they will need to form their own opinion as to the value. We currently have an ideal method of conveying this information to our membership through the Fire and Arson Investigator Journal.

    Results of the

    Florida Serial

    Fire Event Study

    By, Thomas Riley Hall, Ph.D.

    ABSTRACT

    Hidden within the routine respo

    nses of fire departments

    are possible multiple fires set b

    y individuals in a small

    area. An examination of cluste

    rs was accomplished by

    reviewing the National Fire Inci

    dent Reporting System

    (NFIRS) reports from the Florid

    a State Fire Marshal’s

    Division and the Augmented Cr

    iminal Information Support

    System (ACISS) reports provid

    ed by the Florida Division

    of Investigative and Forensic S

    ervices from 1996 to 2018.

    The results of the Florida Serial

    Fire Event Study found

    that the spatial density of a clu

    ster and to a lesser extent

    the distance between fires wer

    e significant predictors of a

    serial incendiary event. The en

    tire study may be found at

    THE PROBLEM OF A

    RSON. Approximately 8% of fires in

    the United States may be arson

    , and

    intentionally set fires are the fou

    rth leading cause of structure fir

    es in the United States [1]. Som

    etimes

    overlooked are other fires in the

    vicinity which may be part of a l

    arger event. Fires that occur with

    in a

    small geographic area are know

    n as fire clusters. The clusters m

    ay be developing or continuing

    at a rate not readily

    apparent because they are hidd

    en in the much more frequent d

    ay-to-day routine events requiri

    ng the response of fire

    departments. However, these c

    lusters represent the signature a

    ctions of serial firesetters. These

    offenders comprise

    one of the least understood crim

    inal categories yet are responsib

    le for property damage and othe

    r crimes far beyond

    that of other types of offenders

    and require far more investigative

    effort [2] [3] [4].

    Clusters of fires represent the m

    ost prevalent and unique signatu

    res of a serial arsonist. Once th

    ese disparate fires are

    recognized and presented to th

    e investigator, showing that they

    are grouped in a meaningful m

    anner, they represent

    clarion events. In this light, the l

    ittle fires preceding the recognit

    ion of an arson cluster become

    important.

    Arsons occur at a rate that is lik

    ely underreported in the availabl

    e statistics [5]. Portions of these

    arsons are found in

    the clusters of fires, which are a

    lso occurring and are reported,

    but with insufficient data to sep

    arate accidental from

    intentional fires. Using 20 years

    of statewide fire reports, an exa

    mination of archival data from th

    ese mandatory reports

    was used to attempt to unpack fi

    re event records to see if there w

    ere any common occurrences r

    ecorded outside of

    the fire itself.

    FIRES IN FLORIDA

    The premise of the study

    is that serial arsonists do

    not erupt and suddenly

    appear in a neighborhood.

    Rather, there may be a

    discernable and logical

    progression before clusters

    become apparent. One

    of the goals of the Florida

    Serial Fire Event Study was

    to examine fire clusters in a

    spatial context.

    Within Florida, in 2015

    there were 49,107 reported

    fires [6]. Approximately

    8.27% of these fires

    are known to be arson,

    with an additional

    15.1% undetermined

    (Table 1). Within the fire

    investigation community,

    an undetermined fire is

    an unfortunate fact and is

    not necessarily rare. What

    it portends is a gap in

    information regarding the

    classification of fires, which

    are either accidental or

    intentional. By implication,

    IAAI Fire Investigation Standards Committee (FISC) by Terry Dawn Hewitt, Esq., Chair

    FISCBulletin BoardBulletin Board"Tell Me Something I Don't Know" about NFPA 921, 2021 Edition

    1. Introduction1Given the importance of the NFPA 921 Guide to Fire and Explosion Investigations to IAAI members, we trust that our readers are acquainting themselves with the new edition. Rather than listing the changes from the 2017 to the 2021 edition, even in a summary fashion, we thought it beneficial to highlight a few of the 2021 edition revisions that in our opinion are noteworthy. We will consider our effort successful if in reading this article, you learn something you did not know but find informative about NFPA 921's latest edition.The 2021 edition of NFPA 921 has been in effect since April 25, 2020. Since then, a Tentative Interim Amendment (TIA) has been issued to make important corrections in the 2021 edition.2 NFPA 921, 2021 ed., together with details of the TIA, are available on the NFPA 921 Document Information Page.3If you want to track all of the changes between the two editions,

    you can study the revision history by reviewing the First Draft Report and Second Draft Report leading up to the 2021 edition. These reports are available on the NFPA 921 Document Information Page, "Current and Prior Editions" tab.4 Note that first and second drafts are presented to the public as part of the document revision process, and hold no weight as authoritative text. Excerpts from these drafts are presented here to give the reader a perspective on the process and rationale for the changes. Trainings such as those available on the IAAI website5 or at the IAAI International Training Conference in Atlantic City April 18-23, 20216 are also great ways to learn about the 2021 edition.Not all revisions are of equal import. Sometimes, even a small revision involving a word or phrase can be consequential, especially in overarching chapters such as Chapter 1 Administration, Chapter 3 Definitions, or Chapter 4 Basic Methodology. These chapters govern the rest of the document. Occasionally, the meaning of a revision cannot fully be understood without consulting the revision history and the committee7 statement. And sometimes, the full impact of either small or large revisions cannot be assessed until they have been implemented in practice or considered by the courts. With this in mind, let us proceed.

    2. "Concepts are Presented at an Elementary Level" — Removed

    Chapter 1 Administration defines the scope, purpose, and application of NFPA 921. Since the 2008 edition of NFPA 921, the "Application" section has contained a caution that many of the scientific or engineering concepts are presented at an introductory8 or elementary9 level, thus noting that it may be necessary to utilize other resources in an investigation. Even though it was true, stating that concepts were presented at an elementary level afforded a potential opportunity to undermine the opinions of someone relying exclusively on NFPA 921. Where an investigator failed to consult materials beyond NFPA 921, this caution provided fodder for criticism or cross-examination.The 2021 edition removed this caution. Here is legislative text showing how the 2021 edition was revised from the 2017 edition:1.3.5 This document is not intended as a comprehensive

    scientific or engineering text. Although many scientific and engineering concepts are presented within the text, the user is cautioned that these concepts are presented at an elementary level and additional technical resources, training, and education may often need to be utilized in an investigation.

    Thus, the committee removed the caveat that NFPA 921 presents concepts at an elementary level, while retaining the recommendation that additional resources "may often need to be utilized in an investigation." This is the committee's substantiation for this change:

    Overall the document has grown to discuss topics beyond the elementary level. When NFPA 921 was first published in 1992 it had 120 pages. The 2017 edition has 426. Stating that the concepts are presented an elementary level does a disservice to the document itself and those who work to improve it and the fire investigation industry. Furthermore, NFPA 1033 [Standard for Qualifications for Fire Investigator] 1.3.7 states that an investigator must have and maintain basic knowledge of 16 topics beyond the high school level. NFPA 1033 A.1.3.7 states that knowledge on the 16 subjects can
